Patent DE-3213189-A1 (DE)
Title: Bag block and process and apparatus for producing it
Inventor: SCHERZ WILHELM
IPC: B31B27/00
Filed: 1982-04-08
Abstract: In a bag block (70), the rear wall (74) of its bag has only a narrow extension (76). In the region of the rear-wall extensions (76), the various bags are connected by means of passage welds (78) which predetermine edge recesses open towards the bag-block edge. These recesses are limited by an essentially solid wall of thermoplastic, on which the single-layer extensions (26) of the bag rear walls are formed linearly. This linear forming point constitutes at the same time a predetermined breaking point, at which the individual bags can be detached from the bag block by exerting a pull. The passage welds (78) project in the form of a conical ring above the surfaces of the bag block (70) and can thus serve at the same time for mounting a bag block in a sectional holding rail. <IMAGE>

Title: Apparatus and process for obtaining copper from slags
Inventor: DIMITROV ISSAJ MICHAJLOV
IPC: C22B15/00
Filed: 1982-09-24
Abstract: To obtain copper from slags in an apparatus to be operated in a relatively non-wearing manner, the said apparatus has zones separated by alternately high and low half partitions. Connecting orifices are provided in the lower part of the half partitions. The connecting orifices of the low half partitions are at the same height. The height of the connecting orifices of the high half partitions increases in the direction of the slag tap. This causes alternate upward and downward flow of the slag which flows away over the low half partitions, with the result that the major part of the copper in the slag passes over into the matte. <IMAGE>

Title: Gas-electric or diesel-electric heating system with high degree of efficiency
Inventor: JAUCH ERNST DIPL PHYS
IPC: F02B3/06
Filed: 1982-10-27
Abstract: This heating system is characterised in that, during combustion of fuels suitable for internal combustion engines, as much energy as possible is converted into heat energy (if this is not anyway the case) or additional heat energy is obtained from the environment. As an internal combustion engine does not only supply the heat of the combustion but also mechanical energy (expansion of heated gases) and this can be partially or completely converted into heat again via a current generator (electric heating devices), a high degree of efficiency is guaranteed. A part of the mechanical energy can be used for the purpose of directly driving a heat pump in order to draw heat from the environment. The design of the system in terms of capacity depends upon the respective local, climatic and seasonal conditions and characteristics.

Title: Method for segmented armature construction in the commutators of electrical rotating machines
Inventor: ZEDTWITZ CARL DIPL ING
IPC: H01R43/06
Filed: 1983-04-28
Abstract: The production of the necessary internal armature and armature hooks on the individual segments of a commutator in accordance with the previously known methods is relatively costly. If the commutator is manufactured from strip material, said material must be pre-rolled and upset in separate processes, and the individual hooks are not scratched on until this has been done. The inside can also be broached in order in this way to produce the webs for upsetting the hooks. The method which is reported here for the patent provides the capability to produce in a single procedure, on commercially-available broaching machines, a copper ring which can be produced both from tubing as well as from strip material by means of a combined broaching/upsetting process [lacuna] the corresponding webs behind the individual segments. A so-called 3-stage tool is involved here, which forms the smooth right-angled webs in the first stage, upsets these webs on the internal diameter in the second stage, and then broaches the minimum required distance between the upsetting points, by means of spacer blades, in the third stage.

Patent DE-3328528-A1 (DE)
Title: Combination elements
Inventor: SCHERRER HERMANN
IPC: E04F15/02
Filed: 1983-08-06
Abstract: The combination elements consist of six square tiles of equal size with a diagonal decorative division on the surface of the elements. The elements correspond to the numbers 1 to 6 and can thus also be designed as a cohesive dice element. The six combination elements can be variably combined behind and alongside each other so that billions of possible combinations and visual designs are produced. The decorations range from ornamental, abstract and organised graphics to figurative depictions of landscapes, animals and many others. FIELDS OF USE are: CONSTRUCTION, ART, HOBBY, DO-IT-YOURSELF and TOY MARKETS. The combination elements can be used industrially as tiles in the building sector for mosaic-type wall, floor and ceiling coverings with trillions of decorative possibilities, and it is also possible, depending on the assembly of the elements, for the decorations to be constantly varied by interchanging the elements with each other or by simply rotating the elements. In the case of glass elements with an appropriate colour decoration, then, a constant selection of new, decorative light effects can be achieved. Also, in ceilings and wall surfaces with relief combination elements, the decorations can be constantly varied or redesigned without any technical problems or major expenditure. In the teaching and educational sectors, the combination elements can be used as a teaching aid. Even a small child from about two years upwards easily learns by playing ... original abstract incomplete.
